- the console 20 has a housing 22 including a base 24 , a keyboard panel portion 26 and a display panel portion 28 .
- the console 20 may be a lighting control console, but the principles of the invention are not limited to this application.
- the keyboard panel 26 supports a number of devices that can be employed by a user for manual input of commands including data and the like.
- a user inputs commands using buttons 30 of a keyboard 32 on the keyboard panel 26 .
- Commands may also be input using a bank of rotary input devices or encoder wheels 34 .
- a small display screen 36 displays legends for the wheels 34 , and buttons 38 accept commands to control the display 36 and functions of wheels 34 .

- the display panel 26 supports a pair of displays 46 and 48 . These may be similar to one another, and each may be a fifteen inch diagonal flat panel liquid crystal display (LCD), although the principles of the invention are applicable to displays of other sizes and types.
- Displays 46 and 48 are functionally divided into upper segments 46 A and 48 A and lower segments 46 B and 48 B, separated by a line of potential division or separation that is not visible on the displays 46 and 48 but is indicated in the drawings by broken line 50 .
- Some or all of the display segments 46 A, 46 B, 48 A and 48 B may be operated as a single unitary display group so that a continuous display is seen on the group.
- segments 46 A and 46 B for example can display a single continuous graphic display.
- Each of the display segments 46 A, 46 B, 48 A and 48 B may also be operated separately on a functionally stand alone basis so that a separate, independent graphic display is seen on any one selected display segment.
- touch screen assemblies 52 and 54 In addition to entering commands using the devices associated with the keyboard panel 26 , the user may also enter commands with touch screen assemblies 52 and 54 overlying the displays 46 and 48 .
- the structures of the two touch screens 52 and 54 may be identical.
- the illustrated console 20 uses resistive touch screens.
- touch screen 52 is representative of both touch screens 52 and 54 and includes a transparent support backing plate 56 to which is adhered a bottom electrical layer 58 .
- a spacer layer 60 separates the bottom electrical layer 58 from a flexible top electrical layer 62 having a flexible protective hard coat top surface 64 .
- Spacer layer 60 includes an array of spacer elements such as dots that normally separate the bottom and top electrical layers 58 and 60 . Touch of a user's finger or a stylus or the like results in electrical contact between layers 58 and 60 at the point of contact. The position of this contact in x and y coordinates is sensed.
- the display 46 or 48 underlying the touch screen 52 or 54 provides a graphic display that is coordinated with the touch screen to facilitate user comprehension and input.
- the touch screens 52 and 54 are segmented and may cooperate with the functional segments 46 A and 46 B of the display 46 and with the functional segments 48 A and 48 B of the display 48 .
- the touch screen 52 includes upper and lower segments 52 A and 52 B
- the touch screen 54 includes upper and lower segments 54 A and 54 B. These segments overlie and are coextensive with the display segments 46 A, 46 B, 48 A and 48 B.
- the bottom electrical layer 56 and the spacer layer 60 are common to the touch screen segments 52 A and 52 B, and may extend generally throughout the entire area of touch screen 52 .
- the top electrical layer 62 is divided into two separate segments 62 A and 62 B separated by a gap 66 .
- Each of the segments 62 A and 62 B is connected to a touch screen controller 68 and can be operated independently of the other.
- Individual segments of the touch screen 54 have the same structure and are also connected to the controller 68 in the same way.
- the top electrical layer 62 of one of the two similar touch screens 52 and 54 is seen in plan view in FIG. 6 .
- the touch screen segments 62 A and 62 B are separated by the gap 66 .
- the gap 66 is preferably very narrow, for example 0.010 inch or less.
- the touch screen controller 68 illustrated schematically in FIG. 6 may be implemented in the microprocessor based operating system of the console 20 or may be a separate device.
- the controller includes memory and a processor and 68 is connected to the four corners 70 , 71 , 72 and 73 of the top screen segment 62 A and to the four corners 74 , 75 , 76 and 77 of the bottom screen segment 62 B.
- the controller 68 is also connected to the common bottom electrical layer 58 .
- the controller 68 is connected in the same way to the elements of the touch screen 54 .
- the controller 68 applies an alternating series of voltage differentials in transverse x and y directions across the corners 70 , 71 , 72 and 73 .
- the layer 58 is used as an x-y position pick up or sensor.
- the controller 68 applies a voltage to corners 70 and 71 and applies ground potential to corners 72 and 73 .
- the voltage applied to layer 58 corresponds to the x position.
- the controller 68 applies a voltage to corners 70 and 72 and applies ground potential to corners 71 and 73 .
- the voltage applied to layer 58 corresponds to the x position.
- each of the other touch screen segments 52 B, 54 A and 54 B is similar.
- the corner voltage applications are sequenced, for example in a repeating sequence of: (1) 70 and 71 voltage- 72 and 73 ground, (2) 70 and 72 voltage- 71 and 73 ground, (3) 74 and 75 voltage- 76 and 77 ground and (4) 74 and 76 voltage- 75 and 77 ground.
- the voltage at the pick up layer 58 is sensed and interpreted in synchronism with this sequence.
- Corners 71 and 74 may be commoned and corners 73 and 76 may be commoned because segments 62 A and 62 B are not energized simultaneously. This permits the use of only seven conductors for operation of both segments of the touch screen 62 . Further information about the construction and operation of resistive touch screens, beyond that helpful for an understanding of the invention, may be found in Dahlin, “Reach Out/and Touch: Designing a Resistive Touch Screen”, CIRCUIT CELLULAR, January, 2000, incorporated herein by reference.
- the segmented touch screen has advantages.
- a conventional touch screen can supply only a single x-y position. If a touch screen is touched in more than one place, spurious inputs are sensed and it is not possible to obtain a useful touch position input.
- With a typical touch screen covering the entire area of an underlying display only a single touch point command can be obtained.
- a segmented touch screen in accordance with this invention a separate touch position input can be obtained for each segment.
- two separate and simultaneous inputs can be obtained and stored in memory in the controller 68 .
- the segmented touch screen 52 or 54 can alternatively be operated as a single, continuous touch screen.
- the gap 66 is narrow enough that it is bridged by finger or stylus contact without any discontinuity. If the touch screen is operating as one screen, the user is not aware of the gap between segments.
- the sensed x-y position information developed in the controller 68 is typically provided to the console operating system for generation and execution of system commands. In the segmented system, the controller 68 can continuously provide x-y position information for each segment 62 A and 62 B, as well as x-y position information for the entire touch screen area. The operating system then has great flexibility in controlling the mode of touch screen operation.
- FIG. 15 is a flow chart of a simplification of a routine used by the controller 68 in providing position information to the operating system of the console 20 .
- the routine starts in block 170 .
- blocks 172 and 174 respectively, the x-y positions for touch screen segments 62 A and 62 B are obtained and stored.
- the operating system of the console 20 under direct or indirect user or software control requests that the touch screen segments 62 A or 62 B operate independently or, alternatively, operate together as a continuous full screen touch screen.
- block 176 is determination is made whether or not full screen operation is requested by the operating system.
- the position information stored at blocks 172 and 174 may be used to find a single x-y position for the overall touch screen. This computation includes finding a single touch position in block 172 or in block 174 .
- this overall position information is sent to the console operating system. If segmented touch screen operation (not full screen) is requested at block 176 , then the separate and independent x-y position information for touch screen segments 62 A ands 62 B is sent to the operating system at blocks 182 and 184 . This routine ends at block 186 . Touch screen information from the touch screen 54 is provided in the same way.
- segmented touch screen Another advantage of the segmented touch screen is that it is not necessary to continuously implement the touch screen operation over the full extent of the display and touch screen area.
- a conventional touch screen is either operating or not operating over its entire area.
- segmented touch screen it is possible to disable or interrupt or redirect the output of any one or more segments of the touch screen area, while continuing to operate any other segment or segments.
- the console 20 accepts one or more docking modules such as the button switch module 80 seen in FIGS. 2-4 .
- Each of the display areas 46 A, 46 B, 48 A and 48 B, with their associated touch screen segments 52 A, 52 B, 54 A and 54 B can be configured to serve as a docking location for a module such as the module 80 .
- a module such as the module 80 can be docked on any of display areas 46 A, 46 B and 48 A.
- Module 80 is seen docked on display area 46 A in FIGS. 2-4 .
- More than one docking module 80 up to three, may be docked on the display areas 46 A, 46 B and 48 A.
- the modules may be similar to one another or may be different in configuration and capability.
- Each docking port 82 includes a multipin electrical port connector 84 .
- the module 80 includes a mating card edge module connector 86 . When the module 80 is docked in position over a display area, its module connector 86 mates with the corresponding port connector 84 as seen in FIG. 4 .
- the module 80 is at least partly transparent so that the user can view the corresponding display through the module.
- the display portion 46 B is viewed through the module 80 . Therefore, when the module 80 is in place, the underlying display portion 46 B can be used to convey information tailored specifically to the module 80 .
- module 80 is a button switch module, the principles of the invention are applicable to modules of other types and configurations.
- Module 80 includes a largely transparent keypad portion 88 with an array of push button switches 90 and a head portion 92 enclosing circuit components 94 .
- the card edge module connector 86 is mounted at the bottom of the head portion 92 .
- a transparent carrier tray 96 supports a printed circuit board 98 having numerous apertures in the region of the keypad portion 88 through which an underlying display can be viewed,
- a spacer grid 100 separates the printed circuit board 98 from a transparent clear lens layer 102 .
- a mounting frame 104 surrounds the edges of the keypad portion 88 of the module 80 .
- the components 94 are enclosed by a cover 106 , and a panel 108 containing graphic information may overlie the cover 106 .
- each pushbutton switch 90 includes a dome switch 110 mounted on the circuit board 98 .
- the dome switches 110 are conventional normally open momentary operating switches that are operated to the closed condition by a downward force applied to the dome.
- Circuit traces on the circuit board 98 extend to all of the dome switches and the circuitry 94 supplies switch operation data through the connectors 86 and 84 to the operating system of the console 20 . Simultaneous switch operations are enabled.
- the lens layer 102 includes an aperture 112 for each switch 90 , aligned with the corresponding dome switch 110 .
- a key cap 114 is captured for vertical movement in each aperture 112 above the corresponding dome switch 110 .
- the dome switch 110 biases the key cap 114 to an upper position. When the user presses down on a key cap 114 , or plurality of key caps 114 , the corresponding dome switch or switches 110 is or are closed.
- the module 80 for user input in place of the touch screen input of the display.
- One advantage is that multiple switches 90 can be operated simultaneously.
- Another advantage is that the user can find the key caps 114 by feel.
- Another advantage is that key switch motion and reaction force from the dome switches provides the user with tactile switch operation feed back.
- the module 80 may be preferred to touch screen input, particularly in applications where the user may not wish to look continuously at the display.
- each push button switch 90 is a legend area 116 of the lens layer 102 .
- Apertures in the circuit board 98 and the spacer grid 100 provide an unobstructed light path between the underlying display 46 B ( FIG. 2 ) and each of the legend areas 116 .
- the display 46 B is operated to provide any desired legends in the areas 116 , one for each push button switch 90 .
- the module may be used for any of a variety of functions, and the legends displayed at the areas 116 can be programmed and selected accordingly.
- the circuitry 94 of the module 80 includes a microprocessor 118 for reading and processing user commands entered using the push button switches 90 , and associated memory 120 including a non volatile memory region 122 for storage of module identity and similar information.
- An interface processor for example a universal serial bus (USB) chip 124 , enables communication through a bus terminal section 126 of the connector 86 .
- the connector 86 includes another locator section 128 . The terminals in locator section 128 are flagged by selective jumpering to ground or by bridging or the like so that when the module 80 is connected to one of the docking ports 82 , the position of the module is uniquely established.
- USB universal serial bus
- a feature of the console 20 is that when a module 80 is docked at one of the docking ports 82 A, 82 B or 82 C, the touch screen segment under the module is disabled. This prevents spurious touch screen signals resulting from contact by the module. For example, in FIG. 2 , with module 80 in place over the display area 46 B, the touch screen section 52 B is disabled.
- the connector 86 includes a module detector or disable section 130 , and when contact is made between a docking port connector 84 and the disable section 130 , the presence of the module is detected and the adjacent touch screen section can be disabled.
- a bus connection is established between the module 80 and a device manager 132 .
- the device manager 132 accesses the identity information in non volatile memory 122 , and enters pertinent information relating to the module in a table in shared memory 134 . The position of the module can also be maintained in memory.
- the shared memory and pertinent information about the module is available to the microprocessor based operating system 136 of the console 20 .
- the operating system 136 receives commands from the devices of the keyboard panel 26 and from the touch screens 46 and 48 .
- the operating system is able to disable any of the touch screen sections 46 A, 46 B, 48 A and 48 B.
- the operating system 136 employs a display controller 137 to control the information displayed on displays 52 and 54 and is able to use display segments 52 A and 52 B and display segments 54 A and 54 B either as a single display space or as separate display spaces.
- Display controller 137 may be implemented in the operating system 136 or may be entirely or in part a separate device.
- FIG. 11 is a flow chart of a simplification of a routine for modifying the console 20 in response to docking of a module 80 .
- the routine starts at block 138 and at block 140 it is determined whether or not a module is present at dock 82 A.
- the operating system can make this determination by accessing table information in shared memory 134 or by interrogating the disable section 130 or the locator section 128 .
- the touch screen segment 52 A is disabled at block 142 .
- the touch screen segment may be disabled by discontinuing energization of the segment or by interrupting or redirecting the touch screen output from the touch screen controller 68 .
- the display section 46 A is appropriated and operated in a module display mode for providing legends for push button switches 90 at legend areas 116 .
- ports 82 B and 82 C are interrogated at blocks 146 and 148 . If a module is present at port 82 B, then touch screen segment 52 B is disabled at block 150 , and display segment 46 B is switched to module display mode at block 152 . If a module is present at port 82 C, then touch screen segment 54 A is disabled at block 154 , and display segment 48 A is switched to module display mode at block 156 .
- the routine ends at block 158 .
- FIG. 12 shows the display 46 in a full screen display mode with no modules in place at ports 82 A or 82 B.
- the entire display space is filled with a single continuous graphic display, in this this illustration a lighting patch data base listing.
- the touch screen segments 52 A and 52 B are enabled and function as single touch screen input area. The user may touch the display 46 at any point and, for example, pull a cursor to the point of touch at an item of the data base listing.
- FIG. 13 shows how the display may be altered when a module 80 is docked at port 82 B.
- the display area 46 A continues to display a portion of the same graphic display seen in FIG. 12 .
- the display segment 46 B is switched to a module display mode where appropriate legends are displayed under the legend areas 116 of the buttons 90 of the module. In this condition, as described above, the touch screen segment 52 B is disabled while the touch screen segment 52 A remains active.
- FIG. 13 shows how the display is altered when modules are present at both ports 82 A and 82 B. Both of the display areas 46 A and 46 B are switched to module mode and each display is independent of the other. Although similar displays are seen in display segments 46 A and 46 B, the two module display modes can be different, with any desired legends used for the button 90 of each module. In this condition, as described above, both touch screen segments 52 A and 52 B are disabled.
- console 20 may have bus ports such as USB ports for connection of other devices such as additional displays, input pointing devices or others.

Abstract
Description
- The present invention relates to improvements in control consoles.
- Known control consoles include general purpose consoles such as personal computers with keyboards, processors, memory and displays, and also include special purpose consoles such as lighting control consoles, process control consoles and others. A conventional console may include user input devices such as keyboards, pointing devices, rotary and linear encoders and others. A conventional console may include one or more displays such as CRT or LCD or plasma displays. A conventional console may include a user input touch screen over one or each different display. Known consoles also typically include an operating system with a processor and memory, along with stand alone or integrated controllers for the display and touch screen
- As the systems controlled by consoles become more complex, the consoles also become more complex, with a requirement for a large number of user inputs such as keyboard keys, encoders of various types and the need to display a large quantity of information. The physical size of dedicated, special purpose consoles such as lighting control consoles is increasing to provide of all the desired functionality. Complexity and large size are disadvantageous in control consoles. It would be desirable to increase the flexibility and customization potential of control consoles, and to optionally provide tactile feel for user input that is not possible with touch screen input.
- A primary object of the present invention is to provide improvements in control consoles. Other objects are to provide a console having segmented display and touch screen capability; to provide a console touch screen capable of producing touch position information at more than one location simultaneously; to provide a console touch screen with segments that can be individually disabled; to provide an improved console that can optionally accept docking user input modules at selected locations; to provide an improved console with automatic docking module detection; to provide a console with display and touch screen segments that can be controlled when a docking module is docked at a docking port to tailor a portion of the display for the module and to disable a touch screen segment under the module; and to provide an improved control console overcoming disadvantages of consoles known in the past.
- In brief, in accordance with the present invention, there is provided a control console including a display and a plurality of module docking ports adjacent the display. A plurality of touch screen segments are on the display. A docking module is receivable at any one of the module docking ports. A module detector is located at each docking ports. A touch screen controller disables one of the touch screen segments in response to a module detection signal from any of the module detectors.
- In brief, also according to the invention there is provided a console including an operating system, display controller and display for displaying information. A touch screen assembly overlies the display. The touch screen assembly includes a plurality of touch screen segments. A touch screen controller is continuously connected to each of the segments. The touch screen controller independently receives touch position information from each of the touch screen segments.

FIGS. 16 and 17 are top plan views of other types of docking modules for the console. - Having reference now to the drawing, and initially to
FIG. 1 , there is illustrated a console generally designated as 20 and constructed in accordance with the principles of the present invention. Theconsole 20 has ahousing 22 including abase 24, akeyboard panel portion 26 and adisplay panel portion 28. Theconsole 20 may be a lighting control console, but the principles of the invention are not limited to this application. - The
keyboard panel 26 supports a number of devices that can be employed by a user for manual input of commands including data and the like. A user inputscommands using buttons 30 of akeyboard 32 on thekeyboard panel 26. Commands may also be input using a bank of rotary input devices orencoder wheels 34. Asmall display screen 36 displays legends for thewheels 34, andbuttons 38 accept commands to control thedisplay 36 and functions ofwheels 34. Commands may also be entered with an additional pair ofencoder wheels 40. Commands may also be entered using a bank of linear input devices orsubmaster faders 42 having functions controlled bybuttons 44. - The
display panel 26 supports a pair ofdisplays Displays upper segments lower segments displays broken line 50. - Some or all of the
display segments segments display segments - In addition to entering commands using the devices associated with the
keyboard panel 26, the user may also enter commands withtouch screen assemblies displays touch screens console 20 uses resistive touch screens. As seen inFIG. 5 ,touch screen 52 is representative of bothtouch screens support backing plate 56 to which is adhered a bottomelectrical layer 58. Aspacer layer 60 separates the bottomelectrical layer 58 from a flexible topelectrical layer 62 having a flexible protective hardcoat top surface 64. - All of the
layers display 46 is visible through thetouch screen 52.Spacer layer 60 includes an array of spacer elements such as dots that normally separate the bottom and topelectrical layers layers display touch screen - The
touch screens functional segments display 46 and with thefunctional segments display 48. Thetouch screen 52 includes upper andlower segments touch screen 54 includes upper andlower segments display segments - Referring again to
FIG. 5 , the bottomelectrical layer 56 and thespacer layer 60 are common to thetouch screen segments touch screen 52. The topelectrical layer 62 is divided into twoseparate segments gap 66. Each of thesegments touch screen controller 68 and can be operated independently of the other. Individual segments of thetouch screen 54 have the same structure and are also connected to thecontroller 68 in the same way. - The top
electrical layer 62 of one of the twosimilar touch screens FIG. 6 . Thetouch screen segments gap 66. Thegap 66 is preferably very narrow, for example 0.010 inch or less. Thetouch screen controller 68 illustrated schematically inFIG. 6 may be implemented in the microprocessor based operating system of theconsole 20 or may be a separate device. The controller includes memory and a processor and 68 is connected to the fourcorners top screen segment 62A and to the fourcorners bottom screen segment 62B. Thecontroller 68 is also connected to the common bottomelectrical layer 58. Thecontroller 68 is connected in the same way to the elements of thetouch screen 54. - For touch screen operation of the
top segment 62A, thecontroller 68 applies an alternating series of voltage differentials in transverse x and y directions across thecorners electrical layer segment 62A and the common bottomelectrical layer 58. Thelayer 58 is used as an x-y position pick up or sensor. To read the x position, thecontroller 68 applies a voltage tocorners corners controller 68 applies a voltage tocorners corners - The operation of each of the other
touch screen segments segments layer 58 is sensed and interpreted in synchronism with this sequence. -
Corners corners segments touch screen 62. Further information about the construction and operation of resistive touch screens, beyond that helpful for an understanding of the invention, may be found in Dahlin, “Reach Out/and Touch: Designing a Resistive Touch Screen”, CIRCUIT CELLULAR, January, 2000, incorporated herein by reference. - The segmented touch screen has advantages. A conventional touch screen can supply only a single x-y position. If a touch screen is touched in more than one place, spurious inputs are sensed and it is not possible to obtain a useful touch position input. With a typical touch screen covering the entire area of an underlying display, only a single touch point command can be obtained. With a segmented touch screen in accordance with this invention, a separate touch position input can be obtained for each segment. Thus, for the touch screen of
FIGS. 5 and 6 , two separate and simultaneous inputs can be obtained and stored in memory in thecontroller 68. - The
segmented touch screen gap 66 is narrow enough that it is bridged by finger or stylus contact without any discontinuity. If the touch screen is operating as one screen, the user is not aware of the gap between segments. The sensed x-y position information developed in thecontroller 68 is typically provided to the console operating system for generation and execution of system commands. In the segmented system, thecontroller 68 can continuously provide x-y position information for eachsegment -
FIG. 15 is a flow chart of a simplification of a routine used by thecontroller 68 in providing position information to the operating system of theconsole 20. The routine starts inblock 170. In blocks 172 and 174 respectively, the x-y positions fortouch screen segments console 20 under direct or indirect user or software control requests that thetouch screen segments block 176 is determination is made whether or not full screen operation is requested by the operating system. - If full screen touch screen operation is requested at
block 176, then inblock 178 the position information stored atblocks block 172 or inblock 174. Atblock 180 this overall position information is sent to the console operating system. If segmented touch screen operation (not full screen) is requested atblock 176, then the separate and independent x-y position information fortouch screen 62B is sent to the operating system atsegments 62A andsblocks block 186. Touch screen information from thetouch screen 54 is provided in the same way. - Another advantage of the segmented touch screen is that it is not necessary to continuously implement the touch screen operation over the full extent of the display and touch screen area. A conventional touch screen is either operating or not operating over its entire area. With the segmented touch screen, it is possible to disable or interrupt or redirect the output of any one or more segments of the touch screen area, while continuing to operate any other segment or segments.
- The
console 20 accepts one or more docking modules such as thebutton switch module 80 seen inFIGS. 2-4 . Each of thedisplay areas touch screen segments module 80. In the illustrated arrangement, a module such as themodule 80 can be docked on any ofdisplay areas Module 80 is seen docked ondisplay area 46A inFIGS. 2-4 . More than onedocking module 80, up to three, may be docked on thedisplay areas - Located to the side of each
display area docking port docking port 82 includes a multipinelectrical port connector 84. Themodule 80 includes a mating cardedge module connector 86. When themodule 80 is docked in position over a display area, itsmodule connector 86 mates with thecorresponding port connector 84 as seen inFIG. 4 . - The
module 80 is at least partly transparent so that the user can view the corresponding display through the module. InFIG. 2 for example, thedisplay portion 46B is viewed through themodule 80. Therefore, when themodule 80 is in place, theunderlying display portion 46B can be used to convey information tailored specifically to themodule 80. - The structure of the
module 80 is best seen inFIGS. 7-9 . Althoughmodule 80 is a button switch module, the principles of the invention are applicable to modules of other types and configurations.Module 80 includes a largelytransparent keypad portion 88 with an array of push button switches 90 and ahead portion 92enclosing circuit components 94. The cardedge module connector 86 is mounted at the bottom of thehead portion 92. As seen inFIG. 8 , atransparent carrier tray 96 supports a printedcircuit board 98 having numerous apertures in the region of thekeypad portion 88 through which an underlying display can be viewed, Aspacer grid 100 separates the printedcircuit board 98 from a transparentclear lens layer 102. A mountingframe 104 surrounds the edges of thekeypad portion 88 of themodule 80. Thecomponents 94 are enclosed by a cover 106, and apanel 108 containing graphic information may overlie the cover 106. - As seen in
FIG. 9 , eachpushbutton switch 90 includes adome switch 110 mounted on thecircuit board 98. The dome switches 110 are conventional normally open momentary operating switches that are operated to the closed condition by a downward force applied to the dome. Circuit traces on thecircuit board 98 extend to all of the dome switches and thecircuitry 94 supplies switch operation data through theconnectors console 20. Simultaneous switch operations are enabled. - The
lens layer 102 includes anaperture 112 for eachswitch 90, aligned with the correspondingdome switch 110. Akey cap 114 is captured for vertical movement in eachaperture 112 above the correspondingdome switch 110. Thedome switch 110 biases thekey cap 114 to an upper position. When the user presses down on akey cap 114, or plurality ofkey caps 114, the corresponding dome switch or switches 110 is or are closed. - There are advantages in using the
module 80 for user input in place of the touch screen input of the display. One advantage is thatmultiple switches 90 can be operated simultaneously. Another advantage is that the user can find thekey caps 114 by feel. Another advantage is that key switch motion and reaction force from the dome switches provides the user with tactile switch operation feed back. For these reasons, themodule 80 may be preferred to touch screen input, particularly in applications where the user may not wish to look continuously at the display. - Above each
push button switch 90 is alegend area 116 of thelens layer 102. Apertures in thecircuit board 98 and thespacer grid 100 provide an unobstructed light path between theunderlying display 46B (FIG. 2 ) and each of thelegend areas 116. Thedisplay 46B is operated to provide any desired legends in theareas 116, one for eachpush button switch 90. The module may be used for any of a variety of functions, and the legends displayed at theareas 116 can be programmed and selected accordingly. - Referring now to the simplified schematic block diagram of
FIG. 10 , thecircuitry 94 of themodule 80 includes amicroprocessor 118 for reading and processing user commands entered using the push button switches 90, and associatedmemory 120 including a nonvolatile memory region 122 for storage of module identity and similar information. An interface processor, for example a universal serial bus (USB)chip 124, enables communication through abus terminal section 126 of theconnector 86. Theconnector 86 includes anotherlocator section 128. The terminals inlocator section 128 are flagged by selective jumpering to ground or by bridging or the like so that when themodule 80 is connected to one of thedocking ports 82, the position of the module is uniquely established. - A feature of the
console 20 is that when amodule 80 is docked at one of thedocking ports FIG. 2 , withmodule 80 in place over thedisplay area 46B, thetouch screen section 52B is disabled. Theconnector 86 includes a module detector or disablesection 130, and when contact is made between adocking port connector 84 and the disablesection 130, the presence of the module is detected and the adjacent touch screen section can be disabled. - When a
module 80 is docked at aport module 80 and adevice manager 132. Thedevice manager 132 accesses the identity information in nonvolatile memory 122, and enters pertinent information relating to the module in a table in sharedmemory 134. The position of the module can also be maintained in memory. The shared memory and pertinent information about the module is available to the microprocessor basedoperating system 136 of theconsole 20. Theoperating system 136 receives commands from the devices of thekeyboard panel 26 and from thetouch screens touch screen sections operating system 136 employs adisplay controller 137 to control the information displayed ondisplays display segments display segments Display controller 137 may be implemented in theoperating system 136 or may be entirely or in part a separate device. - When a module is docked at any one or more of the
docking ports segments segments FIG. 11 is a flow chart of a simplification of a routine for modifying theconsole 20 in response to docking of amodule 80. The routine starts atblock 138 and atblock 140 it is determined whether or not a module is present atdock 82A. The operating system can make this determination by accessing table information in sharedmemory 134 or by interrogating the disablesection 130 or thelocator section 128. - If a module is present at
port 82A, thetouch screen segment 52A is disabled atblock 142. The touch screen segment may be disabled by discontinuing energization of the segment or by interrupting or redirecting the touch screen output from thetouch screen controller 68. Atblock 144, thedisplay section 46A is appropriated and operated in a module display mode for providing legends for push button switches 90 atlegend areas 116. In a similar manner,ports blocks port 82B, thentouch screen segment 52B is disabled atblock 150, anddisplay segment 46B is switched to module display mode atblock 152. If a module is present atport 82C, thentouch screen segment 54A is disabled atblock 154, anddisplay segment 48A is switched to module display mode atblock 156. The routine ends atblock 158. -
FIG. 12 shows thedisplay 46 in a full screen display mode with no modules in place atports touch screen segments display 46 at any point and, for example, pull a cursor to the point of touch at an item of the data base listing. -
FIG. 13 shows how the display may be altered when amodule 80 is docked atport 82B. Thedisplay area 46A continues to display a portion of the same graphic display seen inFIG. 12 . However thedisplay segment 46B is switched to a module display mode where appropriate legends are displayed under thelegend areas 116 of thebuttons 90 of the module. In this condition, as described above, thetouch screen segment 52B is disabled while thetouch screen segment 52A remains active. -
FIG. 13 shows how the display is altered when modules are present at bothports display areas display segments button 90 of each module. In this condition, as described above, bothtouch screen segments - If desired, printed material or other graphic material may be placed under any
module 80 instead of using the corresponding display segment for providing legends for switches 90. If desired theconsole 20 may have bus ports such as USB ports for connection of other devices such as additional displays, input pointing devices or others. -
FIG. 16 illustrates adocking module 280 that may be used with theconsole 20 in place of or in addition to themodule 80 described in detail above.Module 280 includes auser input portion 282 and ahead portion 284. In many respects themodule 280 may be similar to themodule 80, and thehead portion 284 may include circuitry such ascircuitry 94 and a card edge module connector such as theconnector 86. Themodule 282 may be docked at any of thedocking ports 82 of theconsole 20, and interacts with theconsole 20 in the same manner as themodule 80. Themodule 280 includes a number of push button switches 286 and an array of touch sensitive linear input devices orfaders 288. Themodule 280 is at least partly transparent so that the user is able to view the underlying display through the module. Preferably the push button switches 286 and thefaders 288 and/or regions to the sides of thefaders 288 are transparent so that information specific to themodule 280 and its function can be displayed to assist the user. -
FIG. 17 illustrates adocking module 380 that may be used with theconsole 20 in place of or in addition to themodules Module 380 includes auser input portion 382 and ahead portion 384. In many respects themodule 380 may be similar to themodule 80, and thehead portion 384 may include circuitry such ascircuitry 94 and a card edge module connector such as theconnector 86. Themodule 382 may be docked at any of thedocking ports 82 of theconsole 20, and interacts with theconsole 20 in the same manner as themodules module 380 includes a number of push button switches 386 and an array of rotary input devices or encoders faders 388. Themodule 380 is at least partly transparent so that the user is able to view the underlying display through the module. Preferably the push button switches 386 are transparent, andencoders 388 may also be transparent, so that information specific to themodule 380 and its function can be displayed to assist the user. - While the present invention has been described with reference to the details of the embodiments of the invention shown in the drawing, these details are not intended to limit the scope of the invention as claimed in the appended claims.
